Influence of Polar Groups on the Ability of Polymers to Form Nanopenocox when Heated to Reduce the Fire Hazard of Building Materials

Article Preview

Abstract:

The method for estimating the influence of polar groups on the temperature of the onset of the intense thermal degradation of polymers under heating is proposed. This estimate is based on the equation for calculating this value for the entire repeating link proposed earlier [1-4]. The method is computerized and is included as an integral part of the computer program "Cascade" (INEOS RAS). The calculated estimation is carried out for one of the structures of the rejected cycloaliphatic epoxy resin. The most "weak" group was the group –CO–. The temperature of the onset of intensive thermal degradation of this group is 547 K.
